Time for an update. Drilled the tank today. 7 holes. Just had enough life in my diamond hole saw to do it too.
Here, Taking the overflow out. Built out of 3/8" glass to boot, dang sturdy. But not what I was wanting. Oh, and I drilled it in my living room without making a mess. To prove it can be done. Painted it too LOL That's a 52" projection TV for tank size comparison
Went through alot of Olfa blades.
The Silly Putty ring to hold the water. FYI, I used 3 "eggs" to get enough SP for the dam. To mark the hole, I aligned the hole saw where I wanted it, and turned it a little by hand to scratch the circle mark. Then, when I put the hole saw in the drill, I could see where I wanted to be. To start drilling, hold the drill at a slight angle, and hold the saw steady with your fingertips. Slow speed, and ease into the glass. Slowly straigtening out the drill. Med-slow speed, let the weight of the drill do the work, dont push. Took me 15 min I guess, with the last hole closer to 20 because the saw was about wore out. 1/2" glass. That saw has cut through about 5.5" of glass total so far
Here's the 3 COast to Coast overflow holes in the back.
More pics later. Back has first coat of Marine Gloss black on it. Hope to get another coat on tonight before bed.
Forgot to take pics of the bottom holes, but they look the same, only more of them LOL. Was to busy waiting for gthe Dewalt battery to charge up between holes HAHAHA
